Stihl Chainsaw 25: Best Picks for Hardwood (Top 5 Power Tips)

Ever notice how a stack of neatly split firewood just feels satisfying? Like you’ve conquered something primal? I do. And a good chainsaw is your Excalibur in that battle. Today, I’m diving deep into the Stihl MS 251, focusing on how to choose the best one for tackling hardwood, and sharing five power tips to maximize its performance. Let’s get sawing!

Stihl MS 251: Your Hardwood Hero?

The Stihl MS 251. It’s a popular chainsaw, and for good reason. It’s lightweight, relatively affordable, and packs a decent punch. But is it the right chainsaw for your hardwood needs? Let’s figure that out.

Understanding the Stihl MS 251’s Capabilities

The MS 251 typically comes with a 16-inch or 18-inch bar. This is a sweet spot for most homeowners dealing with trees up to about 12-14 inches in diameter. It’s powered by a 45.6 cc engine, delivering around 3 horsepower. This is enough for smaller hardwoods like oak, maple, and ash, but you’ll need to be smart about your technique.

I’ve personally used the MS 251 for years on my property, primarily for clearing fallen trees and preparing firewood. I’ve found it to be reliable and easy to start, even after sitting idle for a few months. Its weight (around 11 pounds) is also a huge plus when you’re spending hours in the woods.

Key Specs for Hardwood Cutting

• Engine Size: 45.6 cc
• Power Output: ~3 HP
• Bar Length: 16″ or 18″ (most common)
• Weight: ~11 lbs (without fuel and bar/chain)
• Fuel Tank Capacity: 12.5 oz
• Oil Tank Capacity: 6.8 oz

The Hardwood Challenge: Why it Matters

Hardwoods are denser and tougher than softwoods like pine or fir. This means they require more power to cut efficiently. Think oak, maple, hickory, and ash – these are the champions of BTU output for firewood, but they’ll also test your chainsaw’s mettle.

I once tried to fell a 20-inch oak with an underpowered electric chainsaw. Let’s just say it was a long afternoon, filled with frustration and a very tired motor. Lesson learned: match the tool to the task!

Stihl MS 251: Ideal Hardwood Scenarios

The MS 251 excels in these hardwood scenarios:

• Cutting firewood from smaller logs (under 12 inches diameter): This is where it shines.
• Felling small trees (under 10 inches diameter): With proper technique, it can handle this.
• Limbing fallen trees: The lightweight design makes it easy to maneuver.
• Occasional use: If you’re not cutting hardwood every day, it’s a good choice.

When to Consider a More Powerful Chainsaw

If you regularly deal with larger hardwood logs (over 12 inches diameter) or fell larger trees, you might want to consider a more powerful chainsaw. Models like the Stihl MS 271 or MS 291 offer more horsepower and longer bar options. A larger saw will make your job safer and more efficient.

Consider these factors:

• Frequency of use: Daily hardwood cutting demands a more robust saw.
• Log diameter: Larger logs require more power and a longer bar.
• Budget: More powerful saws come with a higher price tag.
• Physical strength: Larger saws are heavier and require more strength to operate safely.

Choosing the Right Stihl MS 251 for Hardwood

Not all MS 251s are created equal. Here’s how to pick the best one for tackling hardwood:

Bar Length: Finding the Sweet Spot

The 16-inch bar is generally sufficient for most firewood cutting. However, if you frequently encounter logs closer to the 12-inch diameter mark, the 18-inch bar offers more versatility.

I personally prefer the 18-inch bar because it allows me to cut through larger logs in a single pass, reducing the need for multiple cuts. This saves time and reduces wear and tear on the chainsaw.

Chain Type: Optimizing for Hardwood

The chain is where the rubber meets the road (or, in this case, where the steel meets the wood). For hardwood, you want a chain designed for aggressive cutting.

• Full Chisel Chains: These chains have square-cornered teeth that are very aggressive and cut quickly. However, they dull faster and require more sharpening.
• Semi-Chisel Chains: These chains have rounded-corner teeth that are more durable and stay sharp longer. They cut slower than full chisel chains but are better suited for dirty wood or occasional use.
• Low-Profile Chains: These chains are designed for safety and are less prone to kickback. They are a good choice for beginners but are not as efficient for cutting hardwood.

I recommend using a semi-chisel chain for most hardwood cutting with the MS 251. It offers a good balance of cutting speed and durability.

Features to Look For

• Easy2Start™ System: This makes starting the chainsaw much easier, especially in cold weather.
• Quick Chain Adjuster (B model): This allows you to adjust the chain tension without tools.
• Anti-Vibration System: This reduces fatigue and makes the chainsaw more comfortable to use for extended periods.
• Master Control Lever™: This combines the choke, start, and stop functions into a single lever.

Where to Buy: Authorized Dealers vs. Online Retailers

I always recommend buying from an authorized Stihl dealer. They can provide expert advice, service, and warranty support. While online retailers may offer slightly lower prices, you miss out on the personal service and support of a local dealer.

Plus, authorized dealers are trained to properly assemble and service the chainsaw, ensuring it’s ready to use right out of the box. They can also provide valuable tips on maintenance and safety.

Top 5 Power Tips for Hardwood Cutting with the Stihl MS 251

Okay, you’ve got your MS 251. Now it’s time to unleash its full potential. Here are my top five power tips for cutting hardwood effectively and safely:

1. Sharpen Your Chain Like a Pro

A dull chain is your worst enemy. It not only slows down cutting but also puts unnecessary strain on the engine and increases the risk of kickback.

I sharpen my chain after every few tanks of fuel, or whenever I notice it’s not cutting as smoothly as it should. A sharp chain pulls itself through the wood, while a dull chain requires you to force it.

How to Sharpen Your Chain:

1. Secure the Chainsaw: Clamp the chainsaw in a vise or use a chainsaw vise.
2. Use the Right File: Use a chainsaw file that matches the pitch of your chain. The file size is usually stamped on the chain.
3. Maintain the Correct Angle: Use a file guide to maintain the correct sharpening angle. The angle is usually marked on the file guide.
4. Sharpen Each Tooth Evenly: Sharpen each tooth with the same number of strokes.
5. Lower the Depth Gauges: Use a depth gauge tool to lower the depth gauges after sharpening the chain several times. This helps prevent kickback.

Pro Tip: Invest in a good chainsaw sharpening kit. It will pay for itself in the long run by extending the life of your chain and improving cutting performance.

2. Master the Art of Felling Cuts

Felling a tree safely and efficiently requires proper technique. Don’t just hack away at the trunk and hope for the best!

The Three-Cut Method:

1. Notch Cut: Cut a notch on the side of the tree in the direction you want it to fall. The notch should be about 1/3 of the tree’s diameter.
2. Hinge Cut: Make a horizontal cut on the opposite side of the tree, slightly above the notch. Leave a hinge of wood between the two cuts.
3. Felling Cut: Cut through the hinge until the tree starts to fall.

Important Considerations:

• Lean of the Tree: Always fell the tree in the direction of its natural lean.
• Wind Direction: Be aware of the wind direction and adjust your felling plan accordingly.
• Escape Route: Clear an escape route before you start cutting.
• Bystanders: Keep bystanders at a safe distance.

I once underestimated the lean of a tree and almost had it fall in the wrong direction. Luckily, I was able to correct the situation before it became dangerous. Always take the time to assess the situation and plan your felling cuts carefully.

3. Optimize Your Bucking Technique

Bucking is the process of cutting a felled tree into smaller logs. Here are some tips for bucking hardwood efficiently:

• Support the Log: Place the log on supports to prevent the chain from binding.
• Cut from the Top: Cut from the top of the log to avoid pinching the chain.
• Use a Log Jack: A log jack can help lift the log and make it easier to cut.
• Cut in Stages: For larger logs, cut in stages to prevent the log from splitting.

Preventing Pinching:

• Overcutting: Cut from the top of the log about 1/3 of the way through. Then, cut from the bottom to meet the first cut.
• Undercutting: Cut from the bottom of the log about 1/3 of the way through. Then, cut from the top to meet the first cut.

I’ve found that using a log jack makes bucking much easier and safer. It allows me to lift the log off the ground and avoid pinching the chain.

4. Fuel and Oil: The Lifeblood of Your Chainsaw

Using the right fuel and oil is crucial for the performance and longevity of your chainsaw.

• Fuel: Use a high-quality gasoline with an octane rating of 89 or higher. Mix the gasoline with a 2-cycle engine oil at the ratio recommended by Stihl (usually 50:1).
• Oil: Use a high-quality bar and chain oil. This oil is specifically designed to lubricate the chain and bar and prevent wear.

Important Considerations:

• Fresh Fuel: Use fresh fuel that is no more than 30 days old.
• Proper Mixing: Mix the fuel and oil thoroughly before adding it to the fuel tank.
• Check Oil Level: Check the oil level frequently and refill as needed.

I once ruined a chainsaw engine by using old fuel. The fuel had broken down and clogged the carburetor. Always use fresh fuel and follow the manufacturer’s recommendations for fuel and oil.

5. Maintenance: Keeping Your Chainsaw in Top Condition

Regular maintenance is essential for keeping your chainsaw running smoothly and extending its life.

• Clean the Air Filter: Clean the air filter after every few tanks of fuel. A dirty air filter restricts airflow and reduces engine performance.
• Clean the Spark Plug: Clean the spark plug periodically to ensure proper ignition.
• Check the Chain Tension: Check the chain tension frequently and adjust as needed.
• Lubricate the Sprocket: Lubricate the sprocket after every few tanks of fuel.
• Store Properly: Store the chainsaw in a dry place when not in use.

Maintenance Schedule:

• Daily: Check chain tension, oil level, and air filter.
• Weekly: Clean air filter, spark plug, and lubricate sprocket.
• Monthly: Sharpen chain and inspect bar.
• Annually: Replace spark plug and fuel filter.

I follow a strict maintenance schedule for my chainsaw. This helps me keep it running smoothly and prevents costly repairs.

Safety First: Protecting Yourself While Cutting Hardwood

Chainsaw work is inherently dangerous. Always prioritize safety when cutting hardwood.

Essential Safety Gear

• Helmet: Protects your head from falling branches and debris.
• Eye Protection: Protects your eyes from flying chips and sawdust.
• Hearing Protection: Protects your ears from the loud noise of the chainsaw.
• Gloves: Protect your hands from cuts and abrasions.
• Chainsaw Chaps: Protect your legs from chainsaw cuts.
• Steel-Toed Boots: Protect your feet from falling logs and sharp objects.

I never start my chainsaw without wearing all of my safety gear. It’s not worth risking a serious injury.

Safe Operating Practices

• Read the Manual: Read the chainsaw’s manual carefully before using it.
• Start on the Ground: Start the chainsaw on the ground, not in your hands.
• Maintain a Firm Grip: Maintain a firm grip on the chainsaw with both hands.
• Keep Your Balance: Keep your balance and avoid cutting above your head.
• Be Aware of Your Surroundings: Be aware of your surroundings and watch out for obstacles.
• Never Cut Alone: Never cut alone in case of an emergency.

I always tell people new to chainsaw work: respect the tool. It can be incredibly useful, but also incredibly dangerous if not handled properly.

Understanding and Preventing Kickback

Kickback is a sudden, uncontrolled movement of the chainsaw that can cause serious injury.

Causes of Kickback:

• Contact with the Upper Tip of the Bar: This is the most common cause of kickback.
• Pinching the Chain: Pinching the chain can cause the chainsaw to kick back.
• Cutting with a Dull Chain: A dull chain is more prone to kickback.

Preventing Kickback:

• Use a Chainsaw with Kickback Reduction Features: Some chainsaws have features that reduce the risk of kickback.
• Avoid Contact with the Upper Tip of the Bar: Be aware of the position of the upper tip of the bar and avoid contacting it with the wood.
• Maintain a Sharp Chain: Keep your chain sharp to reduce the risk of kickback.
• Use Proper Cutting Techniques: Use proper cutting techniques to avoid pinching the chain.

I’ve experienced kickback a few times, and it’s a scary experience. Always be aware of the risk of kickback and take steps to prevent it.
